1. Oregon Legislature Floor Speeches

In 2011, a bipartisan effort was undertaken in the Oregon legislature to embed lyrics from "Never Gonna Give You Up" in floor speeches. The result was this nerdy video:

Legislators explained that the planning process involved volunteers, so was budget-neutral.

2. Macy's Thanksgiving Day Parade

In 2008, Rick Astley made an appearance during the Macy's Thanksgiving Day Parade, interrupting a performance by characters from Foster's Home for Imaginary Friends. Enjoy:

3. Speaker Pelosi's Cat Cam

In 2009, House Speaker Nancy Pelosi celebrated the launch of the "HouseHub" YouTube channel by presenting "a behind the scenes view of the Speaker's Office in the US Capitol," mainly involving cats. 35 seconds into the video, something unusual happens.

When the song played, most people booed, though you can hear in this video at least a few people giving a shot at singing along:

9. EWU Basketball

Multiple Eastern Washington University (EWU) women's basketball games experienced pregame Rickrolls in March 2008. A Rick Astley impersonator lip-synched as audience members either danced or ignored the whole thing. The prank was covered by the New York Times. Here's video:

10. Mario PaintRoll

Although not a prank, this deserves inclusion simply for the effort involved. Mario Paint was a Nintendo game that allowed the user to compose songs using various Nintendo icons on a music staff. Here's "Never Gonna Give You Up" arranged for Mario Paint:

11. ThinkGeek Betamax to HD-DVD Converter

On April 1, 2008, online retailer ThinkGeek advertised a stunningly useless product: a Betamax to HD-DVD Converter, complete with a jokey product description and a list of technical features including "Uses electricity." They even posted a YouTube video demonstrating the thing:
